Example for Configuring CPOS Interfaces

Example for Configuring CPOS Interfaces

This example shows how to interconnect devices through CPOS interfaces over an FR network.

Networking Requirements

CPOS interfaces are used to improve the convergence capability of low-speed access for Routers. STM-1 CPOS interfaces are often used to converge multiple E1/T1 interfaces.

At present, some governmental agencies and enterprises use low-end and mid-range devices to access the transmission network through E1/T1 leased lines. Users requiring bandwidth between E1/T1 and T3 (44M), such as the date center, lease several E1/T1 interfaces simultaneously. Bandwidth of these users converges on one or multiple CPOS interfaces through the transmission network. CPOS interfaces are then connected to Device A that identifies each low-end device through timeslots.

In application, there may be more than one level of transmission networks between CPOS interfaces and low-end devices. Other transmission devices are needed to relay communication between low-end devices and transmission networks.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Create the channel.

  2. Create the channel-set.

  3. Bundle the channel into the channel-set.

Data Preparation

To complete the configuration, you need the following data:

  • Channel number and timeslot number of each E1 channel

  • Number of the channel-set of each interface

Procedure

  1. Configure Device A.

    # Create a channel on the CPOS interface.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceA
    [*DeviceA] controller cpos 0/1/0
    [*DeviceA-Cpos0/1/0] e1 1 channel-set 1 timeslot-list 1-10
    [*DeviceA-Cpos0/1/0] e1 2 channel-set 2 timeslot-list 11-15
    [*DeviceA-Cpos0/1/0] e1 3 channel-set 3 timeslot-list 16-20
    [*DeviceA-Cpos0/1/0] e1 4 channel-set 4 timeslot-list 21-30
    [*DeviceA-Cpos0/1/0] undo shutdown
    [*DeviceA-Cpos0/1/0] quit
    [*DeviceA] commit

    # Create a channel-set and configure the endpoint authenticator.

    [~DeviceA] interface mp-group 0/3/0
    [*DeviceA-Mpgroup0/3/0] discriminator
    [*DeviceA-Mpgroup0/3/0] undo shutdown
    [*DeviceA-Mpgroup0/3/0] quit
    [*DeviceA] commit

    # Bundle the channel into the channel-set.

    [~DeviceA] interface Serial 0/1/0/1:1
    [~DeviceA] link-protocol ppp
    [*DeviceA-Serial0/1/0/1:1] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/1/0/1:1] quit
    [*DeviceA] interface Serial 0/1/0/2:2
    [*DeviceA] link-protocol ppp
    [*DeviceA-Serial0/1/0/2:2] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/1/0/2:2] quit
    [*DeviceA] interface Serial 0/1/0/3:3
    [*DeviceA] link-protocol ppp
    [*DeviceA-Serial0/1/0/3:3] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/1/0/3:3] quit
    [*DeviceA] interface Serial 0/1/0/4:4
    [*DeviceA] link-protocol ppp
    [*DeviceA-Serial0/1/0/4:4] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/1/0/4:4] quit
    [*DeviceA] commit

  2. Configure Device B.

    # Create the channel on the E1 interface.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceB
    [*DeviceB] controller E1 0/2/9
    [*DeviceB-E10/2/9] channel-set 0 timeslot-list 1-31
    [*DeviceB-E10/2/9]  undo shutdown
    [*DeviceB-E10/2/9] quit
    [*DeviceB] commit

    # Create a channel-set.

    [~DeviceB] interface mp-group 0/2/9
    [*DeviceB-Mp-group0/2/9] discriminator
    [*DeviceB-Mp-group0/2/9] undo shutdown
    [*DeviceB-Mp-group0/2/9] quit
    [*DeviceB] commit

    # Bundle the channel into the channel-set.

    [~DeviceB] interface Serial0/2/9:0
    [~DeviceA] link-protocol ppp
    [*DeviceB-Serial0/2/9:0] ppp mp mp-group 0/2/9
    [*DeviceB] commit
